Title: Improvements in control devices for travelling bands or webs
IPC: B65H23/04
Filed: 1932-10-25
Abstract: 407,765. Feeding webs. TOOTAL BROADHURST LEE CO., Ltd., 56, Oxford Street, Manchester, and LAURIE, K. S., Dasio, Simmondley New Road, Glossop, Derbyshire. Oct. 25,1932, No. 29817. [Class 100 (i).] A control device for synchronizing machines such as tentering machines acting on webs of cloth &c. comprises a pivoted pendulum guide 2 for the web interposed between two machines, and a relay which is operated by the displacement of the guide to change the speed of either of the machines. The guide 2 is mounted on end bars 3 pivoted like a pendulum to a rigid frame 5. The bars 3 are moved to the right if increased tension is put on the web by the greater speed of the machine in front of the guide, and to the left by the accumulation of the web if the machine behind the guide is moving faster. Motion is transmitted by the bars 3 to the valve in an air chest 10 via a link 6 and levers 7, 9 and air passes from a pipe 12 or 13 to one side of an air cylinder 14, the piston of which has a rod 15 connected to a fork 16 for shifting a belt 17 along a conical pulley 18 which drives one of the machines. A hydraulic servomotor may replace the pneumatic one, and a light bar bearing on one side only of the web may replace the guide 2. When the belt 17 has established equality between the two machines, the rod 15 by means of a Bowden wire 19 operates a rod 22 connected by a link 23 to the lever 7 and cuts off the supply to the servo-motor. In a modification, the link 6 operates a switch which controls electromagnetically the speed of an electric driving motor of either of the two machines, which are thus kept in synchronism.

Title: Process for the manufacture of trialkylacetamides with saturated alkyl groups
Filed: 1936-11-05
Abstract: Trialkyl-acetamides containing 12--17 carbon atoms are prepared by the hydrolysis of nitriles of the formula <FORM:0469921/IV/1> in which R, R<1> and R<11> indicate the same or different saturated alkyl groups, such that in the case of products containing 12 carbon atoms they constitute alkyls with at least 3 carbon atoms, whilst in the case of products with 13--17 carbon atoms they represent any alkyl groups.  The products possess therapeutic properties.  Examples are given of the hydrolysis of (1) di-n-butyl-n-propyl-acetonitrile by means of sulphuric acid at 50 DEG  C., or by heating to 180--200 DEG  C. with water to which sodium diisopropylnaphthalene-b -sulphonate is preferably added as emulsifying agent, or by heating in alcohol solution to 40--60 DEG  C. in the presence of hydrogen peroxide and caustic soda; (2) tri-n-butyl-acetonitrile by boiling with butyl or amyl alcohol in presence of potassium hydroxide, or by heating in an autoclave to 150--160 DEG  C.  Reference is also made to dipropyl-butyl-acetamide, ethyl-diisoamyl-acetamide, ethyl-dihexyl-acetamide and tri-isoamyl-acetamide, and figures are given which show the enhanced therapeutic activity of these trialkyl-acetamides as compared with listed saturated and unsaturated trialkyl-acetamides containing up to 12 carbon atoms.

Title: An endo-radio-sonde
IPC: A61B5/07
Filed: 1962-08-07
Abstract: 999, 858. Measuring electrically. NIPPON ELECTRIC CO. Ltd. Aug. 7, 1962, [Oct. 6, 1961], No.30243/62. Heading G1N. [Also in Division H4] An endo-radio sonde, which has no built-in power supply, but has a tank circuit for receiving an external h.f. signal, a storage capacitor for storing the rectified signal and which operates as a power source for the initiation of oscillation in the tank circuit after interruption of the external signal is characterized in that the oscillation initiation time is controlled by the tank circuit capacitance or inductance which is made dependent on the physical parameter to be measured. Fig. 2 shows a Hartley oscillator circuit containing a transistor 4 and a tank circuit with coils 11 and 2<SP>1</SP> and capacitor 3. On reception by the tank circuit of an external h.f. signal, the rectifying action of transistor 4 charges base storage capacitor 5 and collector capacitor 6. The charging voltage of capacitor 5 is suppressed to a constant value by a Zener diode 7 connected across it while the voltage across capacitor 6 also attains a constant value which is dependent on the inductance ratio of coils 1<SP>1</SP> and 2<SP>1</SP>. On interruption of the h.f. signal, storage capacitor 5 discharges, transistor 4 is shifted from cut-off position and the tank circuit begins to oscillate. Since capacitors 5 and 6 are connected by resistor 9, the oscillation initiation time is dependent on the voltage across capacitor 6 and hence on the inductance ratio of coils 1<SP>1</SP> and 2<SP>1</SP>. By causing the iron core of one of these coils to change position with pressure, telemetering of gastrointestinal pressures can be implemented. An alternative circuit embodying a Colpitts oscillator is described in which the pressure sensitive component is a capacitor. Reference has been directed by the Comptroller to Specification 906,006.

Title: An improved process for making artificial silk by the bobbin system
IPC: D01D7/00
Filed: 1932-10-31
Abstract: <PICT:0392083/IV/1> Freshly spun filaments are led from the precipitating bath over a roller rotating in the direction of progress of the filaments and acting with sliding friction thereon, and are then led to the winding bobbin, the peripheral speed of which is less than that of the friction roller.  The action of the friction roller enables the filaments to be wound at a lower tension than the stretching tension to which they are subjected between the nozzle and the friction roller.  As shown in the drawing, the filaments pass from the precipitating bath 3 over tensioning rods, or friction rollers 4, 5 to a positively driven friction roller 1 which draws the filaments by sliding friction from the nozzle 2.  The filaments then pass to a winding bobbin 6 rotating at a lower peripheral speed than the roller 1 and are wound at a comparatively low tension.  The winding tension may be decreased by increasing the angle with which the filaments embrace the friction roller 1. Specification 300,953, [Class 2 (ii), Cellulose &c.], is referred to.

Abstract: 266,827. Helbig, A. B. Dec. 5, 1925. Pulverulent-fuel burners. - A mix. ture of powdered fuel and air from a supply conduit 1 issues into the furnace through a distributing device 2, Figs. 1 and 2, comprising a cone having in its under surface slots 3 communicating with a number of passages formed by vertical baffle-plate 5. The aggregate area of the passages substantially exceeds the cross-sectional area of the supply conduit so that the velocity of the fuel on entering the furnace is reduced considerably without substantially affecting the uniformity of the mixture. The fuel mixture on issuing from the slots 3 impinges on dispersing bars 4 and passes over parallel cooling pipes 8 arranged below the furnace inlet 6 to prevent premature ignition. The cooling pipes other than those embedded in the furnace walls may be provided with ridge pieces 9. In a modified construction the axis of the cone of the distributor is aligned either with the axis of the supply tube or downwardly inclined relatively thereto. Figs. 6 and 7 show another form of distributor having a cylindrical upper surface but tapered on its lower surface to form a. neck. The baffles 5 extend into the cylindrical part and increase in height from the feed end to the opposite end. The fuel inlet 6 is preferably rectangular, but may be flared. In a modification the cylindrical upper surface is downwardly inclined from the feed end. Fig. 12 show a further modification in which the fuel and air mixture issue from a distributor 2<a> through a conduit 3<a> into a box or chamber 10<a> fixed to the furnace inlet 6<a>, and additional air is supplied through an inlet 11<a> to dilute the fuel and air mixture before it enters the furnace.
